HAL-LEE, 0FVJ'HEELING-pWES-tfi VIRGINIA, ASSIGNOR TO 1 WHEEIJNG BRONZEGS$TING-COMPANY, WK'HEELINGpWEST -VIRGINIA, lA CORPORATION OF WESTVIRGINIA v PICKLING-APPARATUS -FOR RO-DS, -T U-IBES, AND BARSApplication filed August 28, waaseriai This-invention'relates'broadly topickling apparatus,-and more particularly to an apparatus for picklingmetal tubing, rod-s,-shaiting and like-slender orattenuated articles orstrips.

The primary object-of the' inventionis to provide apparatus'o-fthis-character which h'asnovelandimproved means for subjecting theentire surface of the articles to the action of the pickling fluid.

A further object of the invention is to provide a device of thecharactermentioned in which the articles are given-a swinging movement laterallythrough the pickling fluid and, at the'same time, are caused torotate byalternate tipping of the ends of the cradle or carrier in which thearticles are held.

A further object of the invention is to provide pickling apparatus foreffectually loosening and removing scale from the inner walls of tubing.

A still further object of the invention is to provide apparatus of thischaracter, wherein the material to be pickled may be easily and quicklyloaded into and unloaded from the apparatus.

A still further object of the invention is to provide apparatus of thetype mentioned which is of simple and economical construction and whichembodies a minimum of parts that are compactly organized and which areeffective for the ends in view.

In describing the invention in detail, reference is herein had to theaccompanying drawings, in which Fig. 1 is a top plan view of theinvention; Fig. 2 is a side elevation; Fig. 3 is a cross sectional view,illustrating the movements of the arms, links and cradles, and showingthesame in full lines at one extreme of their movements and in dottedlines at the other limit of their movements; and Fig. 4 is a section onthe line 4-4i, Fig. 1, showing the parts during the loading or unloadingof the cradle.

In proceeding in accordance with the present invention, a pickling tank1, conveniently of rectangular form, is provided and is supported onbase members 1'. A series of standards 2 are disposed along each of theN6. 388,949. Renewed August 22', 1931.

' vantageously the bearings are-formed to provide ways 3 which receivethe upper ends' of 'the-standards 2', and bol-ts 3" secure the bearingsin place; A shaft-4 is ournaled in each of the SGIlGS'O-Zl' bearings andisheld thereby above the top of" the tank: Said shafts extendlongitudinally of the tank and have radial arms 5 secured thereto;the-arms 5 =extendinginwardly toward one another.

Links 6 are-pivoted to the inner endssoisai c l arms and dependtherefrom, their lower ends being I pivotal-1y connectedto' the-upwardly projectin g side 'members ofsubstantially U shaped slings 'orcradles 7, sai'd crad le's having theirbottoinsmouglienedor serratedj'as-in'd'i cated at 8, for a purpose' 'latertobe described. At one-endof-the shafts 4, arms=-9 are se cured and depend therefrom"; the arms 9b'e i'ng pivoted to driving links 1O',"w-hi'ch latter ini turnare'pivoted to a crank arm. or -'ee'ce'n'- tric- 11, the element 11being mounted oIra shaft- I2wl1ich is driven through any suitable sourceof power;

In operationy the apparatus is disposedwith the cradles 7 in theposition indicated in Fig-.- 4,- whereupon the rods, tubes,- or" otherarticles M are" placed in the cradles orsli ngs 7, power being thenapplied to'theshaft l2. B'y reterence to Fig. 3, it will be'seen thatthe cradles 7 will thereupon be given a move ment in which saidcradlesare oscillatedor reciprocated laterally of the tank and atthesaine time, theends of the cradles will be alternately tipped, thuscausing the material to gravitate 1 andhave forced rolling move ment, asdistinguished l from-= body-"sliding thereoii withoutrolling. Thus, thematrial is swunglaterally through the fluicl or isbodilyreci-procatedand, due1to thie -alternate tiltingr'of theien'ds of the carrierso'r"cradles=, a Ifloiziced rotatingmovement of the 'material is a Y i Itwill further be notedithat a'tank iof'minimuin Widthcan be employedsince: therange of movement of the c'rad'les (laterally i'ofith'ea tankis -rel'ati vely,a'smal1a; a i 1 u.

It will be understood, of course, that the number of cradles employedcan be varied.

' What is claimed is- V 1. In combination with a pickling tank, a seriesof columns on'each side of the tank, shafts rotatably supported by thecolumns and extending longitudinally of and adjacent to the sides of thetank, radial arms on the shafts extending inwardly in overlying relationto the tank, links pivoted to the inner ends of the arms and dependingtherefrom, substantially U-shaped cradles having their bottoms'roughenedand the upper ends of their sides pivoted to the lower ends of thelinks, a crank arm disposed to aline with thespace centrally between theshafts, arms depending from the shafts, driving links pivoted to thecrank arm and to, the lower ends of the depending arms of the shafts,and means to impart rotary movements to the crank arm. 7 2. Incombination with a pickling tank, a series of columns on each side ofthe tank, shafts rotatably supported by the columns and extendinglongitudinally of and adjacent to the sides of the tank, radial arms onthe shafts extending inwardly in overlying relation to the tank, linkspivoted to the inner ends of the arms and depending therefrom,substantially U-shaped cradles having their bottoms roughened and theupper ends of their sides pivoted to the lower ends of the links, andmeans .to oscillate the shafts in unison whereby to impart a combinedbodily reciprocating movement of the cradles laterally of the tank andalternatetilting of the endsof the cradles.

3..In combination with av pickling fluid containing tank, cradles in thetank to support the material to be pickled, and means to impart acombined bodily reciprocation of the cradles laterally of the tank andal.- ternate tilting of the ends of the cradles.

I 4 In combination with a pickling tank,

cradles in said tank to support the material to be pickled, and means toimpart a combined bodily reciprocation of the cradles laterally of thetank and alternate tilting of theends of the cradles, the bottoms ofsaid cradles being roughened.

5. In combination with a pickling tank, cradles in said tank to supportthe material to be pickled, meanswto'impart a combined bodilyreciprocation of the cradles laterally of the tankand alternate tiltingof the ends of the cradles, and means to cause rolling of the materialupon tilting of the cradles.

V 6. In combination with a pickling fluid containing tank, materialsupporting means in the tank, andmeans to cause swinging of thesupporting means and thereby of the material through the fluid andlaterally of a the tank and simultaneous rotary shifting movement of thematerial.

7 In combination with a pickling fluid material supporting means in saidtank, means to cause combined swinging'of the supporting means laterallyof the tank and simultaneous alternate tiltingof the ends of thesupporting means, and means to cause rolling of the'material.

10. In combination with a pickling tank, material supporting means inthe tank, means for oscillating said supporting means laterally relativeto the tank, and means to effect rolling of the material borne by thesupporting means during the oscillating movements of the latter.

In testimony whereof, I affix my signature.
